Main Direct builds validated contact pipelines and email deliverability infrastructure for teams raising capital, entering new markets and forming high-value partnerships.
Get in touchThree tightly coupled practices: find the right decision-makers, verify them across independent signals, and make sure your message actually lands in the inbox.
Verified email, LinkedIn and phone pipelines for investors, founders and decision-makers. Every contact is cross-checked across independent signals before it reaches your CRM.
Structured maps of fundraising rounds, active funds and project landscapes — so outreach starts from the right counterparties, not from a purchased list.
Domain authentication (SPF / DKIM / DMARC), sending infrastructure setup, sender reputation management and inbox ramp-up programs for business mail.
Main Direct is an independent consultancy operating at the intersection of data engineering and email marketing. We have spent over ten years building outreach infrastructure, enrichment pipelines and deliverability systems for B2B teams.
We work with a small number of clients at a time and take projects where verified data and measurable inbox placement matter more than volume.
